The impossible has happened. Chief Inspector Reg Wexford has retired from the crime force. He and his wife, Dora, now divide their time between Kingsmarkham and a coachhouse in Hampstead, belonging to their actress daughter, Sheila.
Wexford takes great pleasure in his books, but, for all the benefits of a more relaxed lifestyle, he misses being the hand of the law.
The bodies of two women and a man have been discovered in the old coal hole of an attractive house in St John's Wood. None of the corpses carry identification. But the man's jacket pockets contain a string of pearls, a diamond and a sapphire necklace as well as other jewellery valued in the region of �40,000.
